Product Description

The KDS all-metal, low-volume variable-area flowmeter is designed for flow measurement of suitable liquids or gases. It provides indication of the current flow rate in volume or mass per unit of time. The flowmeter consists of a conical stainless steel measuring tube and a vertically movable float. The valve for setting the flow rate is built-in (only for KDS-K/C). The fluid flows from bottom to top through the metering tube of the flow meter. The float is lifted until an annular gap between the measuring cone and the float is produced which corresponds to the flow. The height of the float resulting from the flow rate is transmitted by the permanent magnet in the float through the magnetic tracking system, rotating the pointer axis of the analog indicator unit.
